Title: Method for detecting information from magneto-optical recording medium
Inventor: TSUZUKIYAMA KOUJI
IPC: G11B11/105
Filed: 1991-07-08
Abstract: PURPOSE:To obtain a regenerative signal from a S/N by making light incident on a polarization beam splitter and splitting the light into a P and an S components, and detecting those P and S components by photoelectric detectors respectively. CONSTITUTION:The laser beam emitted by a laser 11 passes through the beam splitter 12 and is converted on a magneto-optical recording medium 1 and the reflected light reflected by the magneto-optical recording medium 1 is changed from linear polarized light to circular polarized light passing through a 1/4-wavelength plate 13. The light which is changed into the circular polarized light is then changed by a polarization beam splitter 14 into circular polarized light, which is split into a P and an S components and detected by the photoelectric detectors 15a and 15b; and the signals of the P component and S component are differentially amplified by a differential amplifier to detect the regenerative signal.

Title: Fluidic flowmeter
Inventor: MURATA NORIHIKO
IPC: G01F1/20
Filed: 1994-07-19
Abstract: PURPOSE:To accurately measure flowrate by forming oscillation output from a signal formed by controlling the phase and frequency zone of fluidic vibration and using it as a fluidic signal representing the flowrate. CONSTITUTION:Fluidic signal (a) from an amplifier 10 is input in a fluidic vibration output conversion means 14. In the means 14, the signal (a) is input in a phase comparator 15 and the phase difference is compared with a reference signal (b) and a voltage corresponding to the phase difference is generated. By impressing this output voltage to a loop filter 16 for comparing the characteristics of the feedback loop, zone is controlled and impressed to a voltage control oscillator 17 as a control voltage VC. The oscillator 17 outputs the signal with oscillation frequency determined by the voltage VC to the comparator 15. In this case, by setting narrow the zone width of the filter 16, the noise included in the voltage VC is reduced and noise of the oscillation output F is also reduced. There is obtained the frequency of the fluidic vibration with low noise through a comparator 13 and the like.

Title: Interference type optical switch
Inventor: WATANABE KAZUAKI
IPC: G02F1/025
Filed: 1989-06-29
Abstract: PURPOSE:To produce the optical switch having high propagation efficiency at a good yield by constituting the clad layers of optical waveguides and optical waveguide layers of the (-) conduction type layers formed by selective epitaxial growth of II-VI compd. semiconductors. CONSTITUTION:After an SiO2 film is formed on a GaAs substrate 1 a part of the film is removed for selective growth, then a mask is formed. The lower clad layer 12 consisting of ZnS, the optical waveguide layer 13 consisting of ZnSe and the upper clad layer 14 consisting of ZnS are selectively epitaxially grown by an MOCVD method to form the layers of the (-) conduction type. Electrodes are deposited by evaporation thereon to obtain the optical switch. Since the optical waveguide layer 13 is formed of the II-VI compds. having a large energy gap, the absorption loss in the waveguide is suppressed small. Since the etching is not executed, the degradation of the film quality is obviated and scattering losses are decreased.

Title: Hydraulic control device in automatic transmitter
Inventor: KUWAYAMA YOSHINARI
IPC: F16H61/00
Filed: 1989-06-29
Abstract: PURPOSE:To reduce a shift shock by looking a band brake in a self-binding direction and non-locking it in an anti-binding direction with the pressure governing port of a modulator valve communicated to the oil pressure chamber for brake locking of hydraulic servo. CONSTITUTION:The modulator pressure of a modulator valve 30 is supplied to the oil pressure chamber 31 for brake locking of a hydraulic servo B1 for a band brake from a pressure governing port 30a, and the rotation of a given element is locked by self boosting force action for a given transmission stage locking the self-binding direction rotation of a given element. In this case, in a different transmission stage, a band brake B1 is required to lock rotation in an anti-binding direction, but the self double force action is not applied in the anti-binding direction, slipping occurs by unsatisfied locking force with low braking capacity caused by modulator pressure, and shifting to a different transmission stage is prevented. Thus a shift via another different transmission stage can be prevented, and the occurrence of a shift shock can be reduced.

Abstract: PURPOSE:To attain new service without giving an effect onto a network by using light in which the intensity of the light of a 1st wavelength is higher than the intensity of the light of a 2nd wavelength so as to multiplex a 1st or a 2nd transmission system. CONSTITUTION:An optical transmitter 1 adopting the intensity modulation sends an optical signal whose wavelength is lambda1 to optical receivers 7-9 of the direct detection system at subscribers. Suppose that the 1st service is offered in the system and a 2nd service is going to be added. The 2nd service is executed by an optical transmitter 20. The optical transmitter 20 sends a light whose wavelength is lambda2 to the subscribers through the transmission of frequency modulation or phase modulation.
